What was the significance of the Japanese attack on Pearl Harbor?

Answer 1

The Doolittle raid was America's first strike back at the Japanese during the war. With Japan running through the Pacific much like the Germans did to Europe in the beginnings of WWII , this was the first opportunity for the US to go on the offensive, with previous battles being solely defensive. We struck the Japanese home land, which Japan thought could not be done by the fact that the US Navy was severly damaged by the attack on Pearl Harbor. It lifted the morale of the entire country by letting the Japanese know that we were down but not defeated.

Answer 2

The destruction was very minimal, but the psychological impact was huge. It showed the Japanese that their homeland was not safe from bombs.

Answer 3

The USA found it really annoying, It brought them into WWII rather then just selling weapons to the protagonists.
